MACHINE-GUN.

SPECIFICATION forming part of Letters Patent No. 711,218, dated October14, 1902.

Application filed May 6, 1901. Renewed August 4,1902. Serial No.118,323. (No model.) I

To all whom it may concern:

. Be it known that l, HENRY H. KRYGE'R, a

' citizen of the United States, residing at Minneapolis, county ofHennepin, and State of Minnesota, have invented new and usefulImprovements in Machine-Gunspf which the following is a specification,reference being firing the said battery, other mean. "or re--leas-ingthe cylinders of the several guns form- 'inafter described.

had to the accompanying drawings.-

My invention relates to firearms; aud'it consists in forming a batteryof short guns (revolvers) adapted to being fired in rapid succession, inconcealing the said battery in a metallic .case, thereby masking theguns to protect them from injury, in means for simultaneously openingthe said case and for ing the battery after the same have beendischarged, and still other means for: removing the cylinders of theseveral guns forming the battery, for forcing the empty shells there-'from, and for returning the said cylinders to their respectivechambers.

The purpose of the invention is the protection of mail and express cars,bank-vaults, office-safes, thetreasure-rooms of vessels, and the like,my mode of application being to place my concealed battery in positidnsto guard the same and when necessary to fire the same from othercompartments of the cars, building, or vessels through the use of meanshere- To these ends my invention consists of the device shown in theaccompanying drawings, in which- Figure 1 is an end view of my battery,(the end of the case being left open and Fig. 2, a top of the same, thetop of thecase being left open, Y

"Similar letters and numerals refer to similar parts in both views,Abeing the guns; B,

,the frame upon which the said guns are I mounted; O, the casein whichthe said frame is concealed; D,

the firing mechanism; E, the cylinder-releasing mechanism, and F theshell-extracting mechanism.

The guns A of which my battery is con structed are of the self-cockingtypes of revolvers, such being best adapted to my purpose. They aresecurely affixed to theframs B by means of the bolts '1. as large aswill enter the case 0, and there- }The frame 15 is .nected at their endsby the angle-irons 3 and 3, the former,3, having its upwardly-extend- Iing portion inwardly curved to conform to the butts of the guns A andserves to hold them securely in place, while the latter, 3,

serves as a foot-rest for the vertical clamps 4,- which in turn clampand support the barrels of the guns A, and also asa support for asprings, which operates to throw open a door 9 of the case 0,hereinafter described. To

the vertical clamps 4 is affixed a spring 6,

which constitutes a part of the firing mechanism D and as such will bedescribed in its order.

To the end rails 2 of the frame 13 are af fixed guides 7, which serve tohold in place a shifting-bar's, which is also a part of the firingmechanism D.

The case 0, I preferably fashion of sheetsteel; but do not confinemyself to any particular. material, my only purpose being to.

have it bullet-proof. It is fashioned with a door 9, hinged at its loweredge, and with a removable cover 10 upon its upper side.

The firing mechanism D consists of the draw-bar 11, the lever 12, therock-shaft 13, the toothed pinion 14, the rack 15, the before-mentionedshifting-bar 8, the lug 16, the

connecting-rod 17, the bell-crank 18, the latch 19, and the spring 5.tends out through the case C and is used in operating (cooking andbattery. To this draw-bar 11 may be affixed a cord or wire, by means ofwhich it is actuated, which cord or wire may extend to anothereompartment of the car, building, or

vessel, or an electric wire may be afiixed there to and the saiddrawrbarbe actuated by electrical energy; but as such'means arecommon-and forni no part of my invention I do not deem it necessary toshow or describe them herein. rock-shaft 1, Which rock-shaft carries atoothed pinion-14, the teeth of which engage those of the rack 15, whichrack is secured to the shifting-bar 8. This shifting-bar 8 car- :ties asmany lugs 16,as there are gunsin the The draw-bar 11 ex firing) theconcealed.

The lever 12 is affixed to the is to actuate the bell-crank 18, onearm'of,

which is terminated in a latch adapted to inlei-lock with a similarlatch 21, affixed to the door 9 of the case 0, and operates (when thesaid connecting-rod is drawn rearward) to release the said latch 19,when the spring 5 (through its reflex action) will throw the door 9open, and at the same time the lugs 16 of the shifting-bar 8 willactuate the several triggers, thereby cooking and firing-the guns.

The spring 6 serves (by its refigx action)-'to throw the bell-crank 18back t its normal position after it has been deflected by the saidconnecting-rod 17, and the spring 23, affixed to the floor ofthe case 0or to some part of the frame B, by bearing against the rear end of theracl; operates to throw the shifting-bar 8, andwith it the rack 15, thelever 12, and the rack 13,'back' to their normal positions after thebattery has been discharged. 7

' The cylinder-releasing mechanism E consists of a suitably-supportedshaft 24, extending the length of the battery, an operatinglever 25,affixed thereto, cams 26, (as many in number as there are guns in thebattery,)

mounted thereon, said cams engaging with and operating catches 27, whichin turn serve .to hold the cylinders of the revolvers within theirrespective chambers. Its operation will hereinafter be set forth.

The shell-extracting mechanism consists of the shiftingbar 28,connecting the several swing-arms 29 of the'guns A, the handle-bar 30,thereunto aflixed, and the shell-extractors 31, (as many as there areguns,) operated thereby. Its operation in connection with thecylinder-releasing mechanism is as follows: After the battery has beendischarged and it is necessary to recharge the several cylinders I graspthe operating-lever 25 of the cylinderreleasing mechanism E and drawitrearward, (to the position shown by' the dotted lines,)

thereby rocking the shaft 24, and with it the cams 26, which in turndraw back the catches 27, thereby u nlocking or releasing the several vcylinders. I then grasp the handle-bar 30 of the shell-extractingmechanism F and with it move the shifting-bar 28 longitudinally in thedirection of the single arrow, thereby moving the swing-arms 29 of theseveral guns, (thus carrying their cylinders out and away from theirrespective chambers,) thence laterally in the direction of the doublearrows to the position shown by the dotted lines, thereby forcing theempty shells out oil their respective chambers through the operation ofthe shell-extractors 31, which in turn are acted upon by the swing-arms29, (now serving as push-pins,) thence in a direction opposite to thatindicated by the double arrows, thereby withdrawing the swing-arms,(push -pins,) thence longitudinally in a direction opposite thatindicated by the single arrow to the point of starting, thereby throwingthe swing-arms 29 to their normal position and carrying the severalcylinders back toand within their respective chambers. i Having thusdescribed my invention, what I claim as new, and desire to secure byLetters Patent, is-

1. In a machine-gun, the combination of the case, a frame therein, gunssecured to the said frame and covered by the said case, and means forsimultaneously opening a door of the said case and for firing the saidguns, substantially as shown and described.

2. In a machine-gun, the combination .with

the, case, a frame'inclosed thereby, guns mounted upon the said frame,and means for firing the said guns; of the cylinder-releasing mechanism,herein shown and described.

3. In a machine-gun the combination with .the case, a frame iuclosedthereby, guns mounted upon the said frame, and means of firing the saidguns; of the shell-extracting mechanism herein shown and described.
